What is Basal Heave Stability in Circular Excavations about?

The document discusses the basal heave stability of circular excavations in clay supported by diaphragm walls. Finite element analyses were carried out to assess the basal heave factor of safety under various conditions. The analyses show that the factor of safety depends on the undrained shear strength of the clay, the geometric properties of the excavation system, and the thickness of the soil stratum. Based on the results, a simplified method is proposed to assess the basal heave factor of safety for axi
